How to build a SOAP request in php?

Question

SOAP

Hello dear experts!
For many days I have been struggling with the formation of a SOAP request and everything is in one place.
The task was set: to get the statuses of applications (
New
Introduced
Negative conclusion
Approved by
the Risk Manager, etc. etc.).
What the developers of the service gave:
- link to the test service for checking the status of the application: https://.................................
- request header

<soapenv:Header>
<UsernameToken xmlns="http://....">ххххххххх</UsernameToken>
<PasswordText xmlns="http://.......">ххххххххх</PasswordText>
<SessionType xmlns="http://.......">ххххх</SessionType>
</soapenv:Header>

-wsdl;
- Examples of applications that you can train on:
1-9CERBS
1-ATXQIR
1-B97NDE.
I ask for help step by step on how to correctly form a request and then get the desired status.
If necessary, I will lay out all my many developments, but I would like to hear from professionals how to start correctly. Thank you.

The service must have a WSDL. It describes all the used methods of the structure, etc. Based on WSDL, code is usually generated in the programming language used. And then everything depends heavily on what kind of language you actually use, but usually the generated code will build everything for you and send it where you need it.
